내 예전 TUR06보다 크게 업그레이드 된 것 같아. 어떤 모델이야?

TU-05

 

[eskamobob1]

Anyone have the TUR-08 and mind sharing impressions/comparisons? Also currious if anyone has tries sus off of one as well tbh

Edit: also currious how similar the sound is to the tur-06? Would the tur-06 give me a solid idea of the "house sound" before I go through the ordeal of getting a tur-08 made?

Anyone know what this is a picture of? I cant find it on their products page

HI,

What is a good place to acquire a Tur-06 amp? (Would be interested if anyone in this group wants to let theirs go as well).

Thanks

These are pretty rare. I had one and sold it a few months ago. You could contact ASP and order from them. https://www.analog2p.com/product/tur06.html

Looks like a new DAC/Amp/Bluetooth offering from ASP. Send an email to them and ask. I don't think they have announced this product yet.

NOS?

Hello everyone!
It's been a while since I've logged in.

Well, this amp is a custom-built DACAMP, using a NosDAC TypeOne, a TR-.
It looks like a combination of the best parts of the 07hp and TUR-06.

The wireless part can be equipped with LDAC or AptX-HD wireless modules.
The size is the same as the 06, and the DAC part is R-2R, so it has high reproducibility of low frequency. SIT was used for the amplification element; SIT (2SK79) is valuable, so it was done in the form of upgrading 07hp. We would like to use Nutube if we make it a standard product.

We wanted to make a product page, but we are busy with other production right now.

You can take orders and the price is 210,000 yen. (appointed day of delivery about 3 month.)

It has 4 XLR outputs and a standard phone output with an output level and impedance of 10Vp-p(3Vrms) 2 ohms. (Uses 4 TO-220 power transistors, same as TUR-08)

It uses the same two 18650 batteries as before, so it can be used for about 8 hours at high power.

Is this current drive if it is part 07hp?

Thanks for reply
This is a voltage drive, not a current drive.
VFETs (SIT) are used for voltage amplification.

tyvm for all of the info! Looks like a very interesting product. Out of curiosity, I know the 07HP is no longer in production. Would it be possible to configure the 07sp to have a HP out? I love current drive amps but am looking for something a technical step up from my bakoon HPA-21 for both susvara and HD800S

 

[CJG888]

Is the DAC section a discrete resistor ladder or a Philips TDA1543 application?

 

[Kageyuki Shikada]

If you want a size of 07hp, you can do it with digital amplifier technology. I'm also experimenting with an amplifier that drives headphones such as HE6se using a housing like 07sp. (Adopts a large TO-3 CAN transistor in Class A) This may not be battery-powered from the standpoint of power consumption.
I'm glad to got the Request. Thank you.

I used TDA1541A for this product.
Since the parts are rare, in the new production, the ready-made R-2R DAC chip or FPGA is used to configure the R-2R ladder.

Hi Adding for future reference, the attached picture is for Tur-06 and the arrows depict low and high gain switches, when shipped it is at medium gain. I got the below information from Shikada while placing an order to use the Tur-06 for headphones and iems and how to get more juice when I use 600 ohms headphones and below change in settings can help.
